I am trying to convert my current application with TPS60120 (200mA max) to TPS61107 to get about 280mA from two cell Ni-MH batteries (~2.4V)
TPS 61107 starts just fine at 3.3V and 140mA load on main output, at this point and can add another 140mA and get stable 3.3V
With any larger startup load 150mA+ I can get on start up only 2.1V
Any ideas why? Does it have anything to do with SKIPEN input that connected to VBAT?
I have a simple test board with 10uH inductor, input cap 22uF ceramic, output caps 2.2uF ceramic and 100uF tantalum
Thanks
